Case Study I: Standard and Funny Isotropic Discs

Abstract

In this chapter, the very simple case of a disc in compression will introduce the reader to the practical implementation of the Virtual Fields Method, and the effect of noise. Linear elastic isotropy is considered to make things as simple as possible. In order to make this example more interesting, one of the discs has a “funny” shape, i.e., it has some cutouts that make it look like a smiling face, whereas the other is a simple circular disc. The reader has to implement very simple virtual fields on exact simulated data, evaluate the influence of noise, and finally process some experimental data.
